• Visual Studio Express Editions Process commands

  Hi, I am writing a program that will start a program at a certain time (I have the time thing working) with parameters And at another set time either send that process a command OR end it Are either of these two possible Cameron. well you use the Process class in the System.Diagnostics namespace to run a process, or its assistant the ProcessStartInfo class, which has additional flexibility like redirecting input/output from the application you are going to run and setting the working directory and setting the window style etc... http://msdn2.microsoft.com/en-us/library/system.diagnostics.process.aspx http://msdn2.microsoft.com/en-us/library/system.diagnostics.processstartinfo.aspx ...Show All

• Visual Studio 2008 (Pre-release) Play a musical note with WPF

  I was recently told that the concept of the MDX (managed direct X) API was obsoleted by Windows Presentation Foundation. So, I went about trying to re-write some of my old MDX code in WPF - and ran into a snag. I need to be able to produce a musical note... and I don't seem be able to do it programmatically any more. Even if I have to simply supply a frequencey and a duration - I can do that since the frequency range of musical notes is well known. Anybody know how to use .NET Framework 3.0 to play a musical note Any help is appreciated. - Thanks! MDX is definitely not obsoleted by WPF. There are some things in WPF that save you from having to use MDX in your apps, but it is not intended to replace it. The answer to your questio ...Show All

• Software Development for Windows Vista Activity Deletion event

  I am looking for something in my rehosted designer that will notify me when an activity is removed from the workflow, then I can remove any bindings to to the deleted activity. I have my own root sequential activity, so I figured that I could just use the OnActivityChangeRemove method, but it is never firing - it doesn't on any of my composite activties either. I looked up the documentation and it doesn't appear to be implemented! Does anyone know how I can be notified when the an activity is deleted from my designer Jason - you can get the IComponentChangeService from the DesignerHost - and then subscribe to the ComponentRemoved event. ...Show All

• Visual Studio Express Editions are methods called asynchronously in the same thread better than those called in another thread?

  i was just wondering since calling methods asynchronously in the same thread acts just like calling the method on another thread. so which is better or preferred by you programmers out there are methods called asynchronously in the same thread better than those called in another thread What I posted may have been a bit confusing: when I said 'begininvoke' will create a thread, I was refering to an asyncdelegate object. When you use 'begininvoke' on a control, it is designed to marshal the call onto the the thread which owns that controls handle. It clearly states this in the documentation. It also states the BeginInvoke is thread safe (which it should be, since it's designed for thread marshalling). There was a reference to a ...Show All

• Visual Studio Could not load file or assembly Microsoft.ReportViewer.ProcessingObjectModel.dll

  My VB .Net Windows application using SQL Reporting runs fine on my development machine.  But when I deploy it to a user's machine and try to run a report, I get the message: Could not load file or assembly Microsoft.ReportViewer.ProcessingObjectModel.dll This file is in the GAC on my machine, but not on the deployment machine.  I tried installing SQL Reporting Services on the deployment machine, but that didn't resolve the problem.  Can someone explain how to get a DLL out of the GAC on one machine so it could be copied over to another one   Thanks. http://go.microsoft.com/fwlink/ LinkId=49981 - says 404. setup.exe created by Visual Studion says the same error, but it worked earlie ...Show All

• Windows Forms Deploy simple unmanaged C++ DLL along with ClickOnce?

  Hi, What is the best way to deploy a simple unmanaged C++ DLL that is called from a C# WinForms app using PInvoke I was thinking about adding the minimum Reg-Free COM stuff to it (without actually needing it) just to make ClickOnce deployment easier. Is that a good idea Anything simpler If ClickOnce doesn't know how to update unmanaged DLLs, what does it do when you update the managed parts of an app deployed with ClickOnce Does it always just recopy and "install" whatever unmanaged DLL is currently in the solution Thanks, Alex Here is what I did.  This seems to work fine. Since I have the sources for this unmanaged C++ DLL I created a second minimal managed C++/CLI project and then included ...Show All

• Windows Forms Control for docked "flyout" (unpinned) panels?

  I'd like to include a pinned/unpinned navigation window in my C# Winforms app that works like the docked windows in the VS05 IDE that are docked on the side with an icon and legend. In the unpinned mode it should open smoothly when you hover over the icon. I'd like to display a treeview in the panel and have the pin/unpin toggle icon as in the IDE. Is there a control that can reproduce this behavior in a Winforms app Edit: I found this: http://xceed.com/Docking_WinForms_Intro.html.  I was hoping to find a free version. I couldn't find a free one, so, for my company, I gave up and wrote my own. It wasn't too terribly difficult...the biggest problem was having to set up mouse hooks to be able to know w ...Show All

• Visual C++ Usage of MC++ class in other .NET languages

  Is it possible to create a MC++ class that uses managed and unmanged code and deploy that class so that it is useable from other managed languages like C# or VB.NET If so how would I go about accomplishing this Yes, this is exactly the place of C++/CLI language in .NET. Create C++/CLI Class Library and write class which exposes pure .NET interface. Internally this class can use unmanaged code, for example, call some unmanaged API. To use this class in C# or VB client, add library reference to the client project and use this class. ...Show All
